Question

the unit vector of a vector is equal to two ICAP + 3 J cap + 4 k cap is

Answer 1

unit vector =a/magnitude of a
=2i+3j+4k/root(2^2 +3^2+4^2)
2i+3j+4k/root(4+9+16)
2i+3j+4k/root29 is answer obtained

Answer 2

$<b><i>$
Heya

Vector A = 2i + 3j + 4k

Magnitude of Vector A=>

= √(2² + 3² + 4²)

= √(4 + 9 + 16)

= √29


Unit vector = Vector A / Magnitude of Vector A

Unit vector A = 2i + 3j + 4k / √29

Hope this helps you.
